TUESDAY SESSIONS SCHEDULE

Engineers have spent countless hours in training on how to design CFS members, but when it comes to the reactions from those members transferring back to the MWFRS structure they are told to use the tables provided by the manufacturers to select a connection. With all the different options available and some having special functions, which do they choose? Which is the most economical for their design? What if you need to use it for a different purpose than shown in the catalog? This presentation is geared to allow the engineers who designed the connectors to explain them, their best functions and what all the fine print below the tables mean. This will allow the engineer to specify the correct connection for the correct situation and avoid mistakes by not understanding the manufacturers’ information.

This session includes a panel consisting of the major manufacturers of clips,connectors and anchors for cold-formed steel construction.

Since the inception of green building programs the steel framing industry has been light years ahead with the environmental attributes of our products.  Recent changes to green building rating systems are now requiring more transparency for products used in the built environment including but not limited to product ingredients, sourcing of raw materials, and other items that speak to the products life cycle.  Many standards are being written to include the development of Environmental Product Declarations, Product Transparency Declarations and Health Product Declarations.  Attend this session to hear firsthand what the steel industry is doing to meet these new requirements.

 9:45 A.M. - 10:30 A.M. BREAK IN EXPO HALL

Moderator: Roger LaBoube, PhD, P.E.
Center for Cold-Formed Steel Structures

This is an open discussion focused on several cold-formed steel design issues that are not fully addressed by codes, standards or industry guidance and, therefore, require some engineering judgment. Designers routinely encounter such challenges, but rarely have the opportunity to discuss solutions with their peers. A panel of experienced cold-formed steel design professionals will lead the discussion and share their insights and practices. Attendees will then be invited to share their experiences.

 Design challenges for discussion:

• Wall studs bearing on concrete
• Design of built-up sections  
• Amount of gravity load applied to a shear wall boundary stud
• Floor vibration for cold-formed steel floor systems                         

 As time allows, the moderator will facilitate an open forum to identify additional topics for discussion at this or a future CFS Design Forum.

Systems, Inc., St. Paul, MN, Prior to ECS, he gained a solid background in cold-formed steel framing design as a project engineer for Inryco, Inc., Milcor Division, a major manufacturer of structural cold-formed steel products. He is a member of the AISI Committee on Specifications and Committee on Framing Standards where he serves on numerous subcommittees, The Steel Framing Alliance, Cold-Formed Steel Engineers Institute, and the American Society of Civil Engineers. He is the past Chairman of the AISI COFS High Wind Subcommittee. A member of CFSEI, he served and National President from 2009 to 2010 and is currently serving as a member of the CFSEI Technical Review Committee. John is a 1981 graduate of the University of Wisconsin-Madison with a Bachelor of Science degree in Civil and Environmental Engineering. He is a registered Professional Engineer in Wisconsin and eighteen other states.

Over the last few years anchors and code reports have been updated to accommodate the new requirements of ACI for anchorage into concrete. For years this has been a simple selection from a table, but now it is more complex. Many times you will complete your exterior wall design with the suction wind forces on the wall or jambs to find out there isn’t an anchor that will work for your situation. Now what do you do? Do you increase your wall thickness just to get more edge distance? Design a special clip that will meet your loads and provide the edge distance needed for the anchor? Add more clips, but then anchor spacing becomes an issue? This presentation will explain the edge distance issues, break down the code reports and help you find a solution of how to anchor with little edge distance and high loading perpendicular to the concrete edge.

Jennifer Zabik is President of Zabik-Turner Engineering. She has been practicing structural engineering for nearly 10 years in the state of Florida and is registered in Florida, Alabama, North Carolina, South Carolina, Tennessee, Kentucky, Louisiana, Georgia, Pennsylvania, Wisconsin, and Illinois & Puerto Rico. She served as the President for the CFSEI – Florida Chapter President from 2010 – 2012. In addition to her cold formed steel involvement she is also on the board of directors for the ASCE-SEI East Central Branch. While obtaining her Master’s degree she co-authored the monograph “Bracing Cold Formed Steel: A Design Guide” with Dr. Thomas Sputo, P.E., S.E.

 Although cold-formed steel (CFS) trusses often represent an economical roof framing option for buildings with pitched roofs, CFS trusses are not included as a conventional construction option in the most recent version of UFC 4-010-01 DoD Minimum Antiterrorism Standards for Buildings.  For roof framing systems in Department of Defense (DoD) facilities not able to be deemed conventional construction, the UFC requires that analysis be performed to demonstrate the UFC-required level of protection.  This session provides an overview of several analytical methods that can be employed to compute CFS truss response under blast loading.  Both single degree-of-freedom and transient nonlinear finite element analysis methods are presented, including attendant assumptions, boundary condition considerations, and limitations associated with each.  In addition, response limits corresponding to DoD levels of protection are proposed for CFS trusses based on a survey of available standards and test data.

Mark Weaver is a Senior Engineer at Karagozian & Case, Inc. (K&C) where he utilizes engineering and computational methods to analyze and design a wide variety of structural components to resist the effects of blast and impact loads.  His experience includes the design of new blast resistant window, door, wall, and roof systems using single degree-of-freedom and high-fidelity physics-based finite element models.  As part of this work, Mr. Weaver has investigated the performance and potential failure modes of cold-formed steel systems via quasi-static laboratory and live-fire field testing.  In addition, he has served as the blast engineering consultant for a number of federal and commercial projects in the US and overseas.  He is highly experienced with the application of the Unified Facilities Criteria (UFC), particularly UFC 4-010-01, UFC 3-340-01, and UFC 3-340-02, and the analytical methods described within.

Prior to his time at K&C, Mr. Weaver worked as a structural design engineer for the Structural-Marine group of Whitman, Requardt, and Associates (WR&A), a full service engineering, architectural, and planning firm located in Baltimore, Maryland.  During his time at WR&A, Mr. Weaver performed the structural design and construction administration duties for a wide variety of projects in the marine, industrial, and institutional sectors.

Mr. Weaver graduated from the University of Southern California with Magna Cum Laude honors and went on to receive both his Master of Civil Engineering and Master of Engineering Management from The Johns Hopkins University and Duke University, respectively.  He is a licensed Professional Engineer (Civil) and Structural Engineer in the state of California.
